1. describe what difference if any there would be between the boiling point of alcohol measured in Houston and in Denver (the mile high city)

The boiling point of alcohol in Houston and Denver will vary as a result of the difference in atmospheric pressure.

The boiling point of  a compound at a particular location depends on the

atmospheric pressure of that location. The lower the atmospheric pressure

of a given place or area, the lower the boiling point and vice versa.

In Denver (the mile high city), alcohol will boil at a lower temperature as a

result of its higher altitude than in Houston because atmospheric pressure

decreases with increase in height and vice versa.

Explanation:

The boiling point of  a substance at a location depends mostly on the atmospheric pressure in that location. The lower the atmospheric pressure in a location, the lower the boiling point and vice versa.

Boiling point is defined as the temperature at which the vapor pressure of the liquid becomes equal to the atmospheric pressure.

In Denver (the mile high city), alcohol will boil at a lower temperature(due to its high altitude) than in Houston because pressure decreases with height.
